To'all wltoin-itimay concerni Be it known that I, HENRY M. .REIs, of the city and county of Philadelphia and State of Pennsylvania, have-invented a new and useful Improvementin an Electric Bank-Protector,

by-declare the following to be a clear and exact description of the nature thereof sufficient invention appertains to fully understand, make, and'use the same, reference being had to the accompanying drawings, making part of this Figurel is a front of'a bank or other building and a'police station.

Similar letters of reference indicate corre My invention has for its object the communication of a bank or other building with a potion, or he mayrannounce at the latter the need ofshelp. For this purpose there will be an electric communication between the bank and anindicator operated, as will be hereinafter set forth. e e

Referring to the drawings, A represents an protected, and B a room of the police-station, which communicate by means of an electric wire, A, extending above or below ground in any well-known manner, the key O being located in the apartmentA, so as to be most B there is pivoted a rotating disk, D, in which stud, lug, or other connection, F, with one end of a dog, G, pivoted to the wall, or a plate, H, thereon, so that the motion of the dog in one directionjwill rotate the disk. At :the other end of the (log G there is pivoted a to'e, J,

hammer K of a gong, L, so that onthe motion of the dog said toe will press against the pin and force the hammer from the gong. Then, when the toe clears said pin a, the hammer is free to return to its first position, and, by the action of'a spring, I), the hammer will strike.

As soon as the key 0 is operated the dogG will be moved, the gong struck, and the disk promptly known.

the gong, and thus an alarm will be sounded. M represents an armature, one part of which is connected to the dog G, and the other part v to a magnet attached to the wire A, whereby,

when the armature is attracted, the dog G will receive motion sous to operate the disk D and bell-hammer K, as stated, the circuit being formed bythe watchman-operating thekey U. On the plate H there will be painted or otherwise indicatedthe figure of an eye, N, which. when the apparatus is set, will be concealed by the plate; but when the disk is rotated the opening E thereto reaches said figure and uncovers the same, so that it will be exposed, as seen inFigs. 2 and 3.

The number of disks and of the gongs, if so desired, will be equal to the number of banks orbuildings to be protected.

The nature of the signals and. the time of signaling will be understood by a preconcerted arrangement between the bank and police offirotated. Wherever there is an eye, N, uncovered and facing the police, the name of the bank whence the signal was sent will be The police may then restore the disk to its normal position and await the next signal.

Should the signal be incorrect in the event i has tripped the pin it stands over the latter, as in Fig.3. Consequently, if the key is operated the gong will not be sounded, and, owing to the position of thepin or lug F, the disk D cannot be moved. This provision will also be of service, since that the bank robbers or any unauthorized persons may be aware of the num- If the watchman neglects to signal at the ber of signals; but not of theintervals-between Having-thus described my invention, What thcinx I'claii n as new, and desire to secure by.
